Double Bottom

Double Bottoms are reversal patterns very similar to the bottom head and shoulders pattern, and are often seen when trading currencies. Double Bottom patterns are identified by two low prices of the same depth with a medium pullback in between.

Double bottoms can be a major reversal pattern that often follow an extended downtrend. When you confirm this pattern is occurring, and there is a significant amount of volume during the uptrend, it is time to “go long”.


Here is the general form of a double bottom pattern. As with most technical analysis patterns, they are a guideline but can differ from this graph to an extent. What is important to note is:

  1. The pattern begins with a strong down trend (the stronger the trend, the better the reversal)
  2. The bottom points should be roughly at the same height (most consider roughly 10 – 20% to be acceptable)
  3. At the second circle on the picture above, the line should be traced at the top of the pullback.
  4. Many consider the height (h in the digram) to be the height that the trend will go above the top line and will place their limit or stop orders accordingly.

There should also be significant volume when the stock breaks upward; you can get a “False Flag” if you see something resembling this pattern, but no increase in volume near the end to signal the reversal is real.
